This novel by Seton's own historian, Bruce T. Clark, takes the reader on a wild ride that contains deadly Aztec sacrifices, wary conquistadors, the call of bugles, and the clash of saber meeting tomahawk. It's a history-mystery in which the reader meets such real-life figures as Cortez, Custer, and Crazy Horse, while sharing the adventures of an Irish soldier of fortune, a white/Indian warrior from the Virginia Military Institute, and the "detective from the Vatican" whose job it is to finally unravel all of the mysteries and recover the Custer Legacy. 575 pp.
